Idle

Added in version 7.0.0

SparkScan is displaying only the collapsed capture button.

Inactive

Added in version 7.0.0

SparkScan is displaying an expanded capture button, and if the SparkScanPreviewBehavior of the current SparkScanScanningMode is SparkScanPreviewBehavior.Persistent, we are also displaying camera feed through the mini preview but no actual scanning is taking place. This state is reachable after scanning or after a SparkScanViewSettings.inactiveStateTimeout timeout.

Active

Added in version 7.0.0

We are actively recognising barcodes, mini preview and expanded capture button are visible.

Error

Added in version 7.0.0

User returns SparkScanBarcodeFeedback.Error from the SparkScanView.feedbackDelegate. Mini preview is visible with a frozen frame and expanded capture button is visible. If capture button is tapped or after a SparkScanBarcodeErrorFeedback.resumeCapturingDelay timeout is reached we move to Active state.
